This is amazing. Not only has Google just opened up the pre-order program for Google Glass to 'creative individuals', it has also unveiled what the user interface looks like and how it works. It's... Nothing short of amazing. I'm throwing money, credit cards, my car keys, my house keys, my Surface RT, my cats, everything at my screen. I want this so bad.

Of course it's no different. You can do the same with any phone - including the iPhone - and it has been that way for almost a decade. Nothing new.

But it's from Google so better make some snide remark about advertising even while their own site uses advertising and tracking as well.

It's totally different. It's the difference between capable and easily capable, not mention discrete. Sure, you can do the same thing now and even years ago, but you can't capture video just by looking at someone--you have to get your phone out, access it's camera, aim it at your subject, etc. It's not discreet, and if you started recording videos of strangers for an extended period of time, someone's probably going to ask you what the eff you're doing.

Will that stop this from progressing? Maybe not. But, social consequences are a consideration and certainly have--and will continue--to influence the adoption of a technology.
